I am so glad I asked the question and thank everyone for their answers. All of your quilts are beautiful. Thank you for posting pictures for me to see. After seeing your results (absolutely beautiful quilts) I am inclined to take a chance and not prewash. However, I did prewash for this one I am starting and then will compare to one that was done without prewashing and decide if I am willing to take the risk. Right now the temptation to be able too buy and start right away is too strong but we will see. I know it is a personal preference but was so nice to hear all your opinions and see all your gorgeous quilts. This is my only outlet to discuss or show off my quilts so thank you all very much.
